The VLT Visitor Focus

One Nasmyth focus (Nasmyth B on UT3-Melipal) on the ESO VLT has been reserved since 2002 for Visitor Instruments (VI) to permit innovative observations by instrument teams using their own stand-alone instruments. VI are free from a substantial fraction of the requirements imposed on the fully automated VLT facility instruments. In addition, VIs could provide a powerful scientific or technical test bench for new instrumental concepts, which may eventually be incorporated later in VLT or other instruments.

Teams that want to propose the use of their VI should follow these instructions.

The technical requirements imposed by ESO on VIs are available here. See also our Gallery.

The VLT already hosted several VIs:

November 2005

DAZLE November 2006
